To all whom it may concern:

Be it known that I BENJAMIN L. TKO]?- SON a citizen of the at lioanbke, in the countyof Roanoke and State of Virginia, have invented certain new and useful Improvements in Electric-Light- Bulb Stabilizers, of which the, following is a s ecification.

'lhis inventionaurelaites todthfat class 1112f stabilizers es 'esigne or sta ing electric 112:; blilbs, and has for its object to prevent the vibration of an electric light bulb which vibration has a tendency to destroy. the cement forming the union betweenthe bulb and the metallic socket in which the bulb is secured and which vibra- {233% also breaks the filaments within the The stabilizer is particularly adapted to use with electriclight bulbs 1n locomotive cabs orother places where vibration attendsri i i ed r 1 lengh e evlceisorm oasmge of wire bent into substantially the shape of the letter U, and the wire so coiled intermediate the ends of the side members as v to form tractile springs therein with the bottom or closed end porti'on'looped upon itself in such manner as to form a ring lying at right angles to the side members to center the bottom of an electric light bulb therein, and the wire being further looped upon itself in such manner as to form a ring-like portion at right angles to the centering ring and rotruding beyond thus forming a gri whic may be grasped by the fingers to a just the centering r1 around the protubery found on the outer ends of electric light bulbs while the wire at the outer ends of the side members ,is bent in such manner hare) tohfzrl'lm hacks for engagin a rturest -esiewalls of the bul socket. -'In )1d81 that. those skilled in the art to which my invention pertains, I will now proceed to describeit with reference to the accompan drawings which form a part of this spec' cation, and in which:

Figure 1,-isa perspective view of the invention.

ilnited States, residing Fig. 2 is a side elevation of an electric li ht bulb with the device applied thereto.

ig. 3 is a view taken at right angles to Fig. 2 and shows the means of centering the electric light bulb.

For a more particular descri tion of the device reference may be had to e reference characters of the drawings which reference characters represent like parts of the structure throughout the drawings, and, in which, reference character 1 represents the side members of the stabilizer with springs 2 interposed therein and intermediate the ends thereof. 3 are the hooked ends of the side members which are adapted to be passed through apertures in the side walls of the socket 4. 5 is the centering at the lower extremity of the stabilizer or encircling and centering therein the protuberance 6 of incandescentbulb 7. 8 is the or handle for conveniently grasping wit the fingers to adjust the centering ring 5 about the protuberance 6.

From th foregoing description it will be readily seen that the device 18 simple, efiective andeconomical of manufacture and will .efiectually hold an electric light bulb under vibration thereof.

Having thus described my invention what I claim is:

In an electric light bulb stabilizer, the combination with an electric hght bulb socket of an electric li ht'bulb, a substantially U shaped stran e yieldable me1 nber adapted to engage said socket with its inner ends, and pass longitudinall around said bulb, means for centering sai bulb 1n the outer portion of said strand and a dependent member carried below said centerm means.

testimony whereof I afix my signature.
